I 4 solaires. (cino- 148)` v im' 'lhepresent invention relates lto wirestraightening or killing devices and embodies,v more parparent as it; isdescribed inY greater detail in v'connection with the accompanyingdrawing,

ticularly, a. straightening or killing device that v,

A permits the wire to be operated upon without subjecting the wire to a,permanent set."

More particularly, the invention embodies a deviceI of the abovecharacter thatis particularly wherein:

Fig. 1 is a plan view showing awire straightening or killing deviceconstructed in accordance with' the present invention.

well adapted to be used with continuous wire f dra ing machines andoperations and wherein a p rmanent set in the wire is avoided.

In continuous wire drawing operations, there is a tendency for internalstrains to accumulate Wwithin the wire. resulting in the wires becomingunmanageable by reason of its taking a permafnent set a ound'the wiredrawing blocks.

` When a coil of such wire is released and allowed to lie flat on thefloor, the excess curvature or corkscrew condition present in the wirewhen first confined in a coilabout the drawing block, causes the wire tobecome unruly, and when the wire is released from the confining bands,it

That

tends to form corkscrews and become otherwise I tangled.

A straightened or killed wire, on theother hand, has a curvature notmuch exceeding that of theJwire when first confined in a coil, and ifthe wire is released on the floorit will remain in approximately oneplane and will not tendtc form corkscrews or become tangled. The"straightenng or killing of wire thus-elimiinates its otherwise normaltendency toward unruly behavior.

AAn object of the present invention is to provide a straightening orkilling device by means of which wire may be straightened or killedeffectively and without the difficulties attendant upon thel presence ofa permanent set formed in the wire. y

A further object of the invention is to provide a wire straightening orkilling device wherein the straightening or killing operation is per-.formed without,` imparting a'permanent set to the` wire.

The foregoing objects are attained by providing l Further objects of theinvention will be ap- 'r Fig.v 2 isa view in front elevation of thedevice of Fig.V 1.

Fig. 3 is a view in transverse section, taken on the line 3-3 of Figl 2and looking in the direction of the arrows.

Referring tothe above drawing, the wire drawing' device is shown asbeing formed with a base `It) having an elongated boss Il which isprovided A flange I8 may be provided and formed with an aperture I9 bymeans of which the base may be securely mounted in position. At theother end of the base, threaded apertures 20 and 2I are provided bymeans of which av cooling fluid may be introduced into and withdrawnfrom the base. In order that the circulation of the fluid may beaccomplished in a desired fashion, the aperspindles and the base.

ture `2I communicates with the compartment,

and suitable'gasket or sealing material 25 provided toinsure a fluidtight Joint between the spindles are formed with axially hollow portions26 and apertures 21 to facilitate movement of the 4cooling fluid into thspindles to effect the cooling thereof.

Rollers 28 are journaled on therspindles by means of roller bearings 29,the `rollers being formed with grooves 30 over which the wire passes asindicated by the dot-and-dash line in Fig. 1. Counter pins 3| may beprovided to secure the rollers in position on the spindles 22 and, inoperation, the wire is drawn through the rollers to effect thestraightening or klling thereof in accordance with well known practice.The circulation, of a cooling lfluid through the base maintains thespindles and rollers at such a temperature that undesirable heating ofthe drawing, it is not to be limited save as defined inthe appendedclaims.

I claim: 1. A wire straightening or killing device comprising a`base, aplurality of spindles carried -by the base, rollersy on the spindlesover which wire is passed to effect the straightening or killingthereof, said spindles and base being hollow, and

means to introduce a cooling fluid into the base and spindles.

2. A wire straightening or killing device comprising a hollow base, aplurality of hollow spindles on the base and having the hollow portionsthereof communicating with the hollow portion of the base, means on thespindles over which wire is passed to effect the straightening orkilling thereof, and means to circulate a cooling uid through the base.

3. A wire straightening o'r killing device comprising a hollow base, aplurality of hollow spindles on the base and having the hollow portionsthereof communicating with the hollow portion of the base, rollersjournaled on the spindles over which wire is passed to eiect thestraightening or killing thereof;v and means to circulate a coolingfluid through the base.

4. A wire straightening or killing device comprising a hollow base, aplurality of hollow spindles on the base, and having the hollow portionsthereof communicating with the hollow portion of the base, rollersjournaled on the spindles over which wire is passed to effect thestraightening or killing thereof, a baiiie in the base, and means tocirculate a cooling fluid through the base, said baille directing theflow of the fluid along the spindles.

5. A wire straightening or killing device comprising a hollow base, aplurality of spindles on the base with a portion of each spindleextending into the hollow portion of the base, means on the spindlesover which wire is passed to effect the straightening or killingthereof, and means to circulate a cooling fluid through the base and incontact with` the spindles.

6. A wire straightening or killing device com,- prising a, hollow base,a plurality of hollow spin'- dles on the base with a portion of eachextending into and having the hollow interiors thereof communicatingwith the hollow portion of the base, means on the spindles over whichwire is passed to eect the rstraightening or killing thereof, and

means to circulate-a cooling fluid through the4 base and along thespindles.

7. A lwire straighteningor killing device coinprising a hollow base, aplurality of spindles on the base with a portion of each spindleextending into the hollow portion of the base, means on the spindlesover which wire is passed to effect` the straightening or killingthereof, the extended portion of each spindle being provided with apassage therethrough, and means to introduce a cooling uid into saidbase for circulation in contact with the extended portions of saidspindles and through the passages contained therein. y

8. A Wire straightening or killing device comprising a hollow base, aplurality of hollow spindles on the base with a portion ofeach extendinginto and having the hollow interiors thereof communicating with thehollow portion of the base, means on the spindles over winch wire ispassed to effect the straightening or killing thereof, the hollowinteriors of said spindles extending into the portion of the spindlesadjacent which the wire is passed, and means to introduce a coolingfluid into 'said base for circulation about the extended portions ofsaid spindles and into the hollow interiors thereof.
